The range of repositories from which the documents have been procured is also considerable. Many were found in the state archives of Massachusetts, many in the files of the Supreme Judicial Court for Suffolk County, many in the collections of the Massachusetts Historical Society, others in the archives of Rhode Island and New York, in the office of the surrogate of New York City, and in the New York Public Library. A very important source of material, indispensable indeed for certain classes of document, was the records and papers of the vice-admiralty courts of the colonial period. Extensive portions still remain in the case of four of these courts, at Boston, New York, Philadelphia, and Charleston (see the first foot-notes to docs. no. 126, no. 184, no. 165, and no. 106, respectively). A large number of the documents, larger indeed than from any other repository but one, were drawn from the inexhaustible stores of the Public Record Office in London, namely, from the Admiralty and Colonial Office Papers. Others came from the Privy Council Office; a few, but among them two of the longest and most interesting, from among the Sloane and Harleian manuscripts in the British Museum; one whole group from the Rawlinson manuscripts in the Bodleian Library at Oxford. Three of the Kidd documents were obtained from among the manuscripts of the Duke of Portland at Welbeck Abbey. Several of the pieces, and a number of lesser extracts used in annotations, were taken from colonial newspapers, and two from printed books not often seen.
